	<h2>At the bank</h2>
	<p>
		The tellers couldn&apos;t help me claim my bill credit, as expected.
		They had me wait for a banker.
		I was waiting about an hour; I literally watched one of the tellers get sent on their lunch break, which was ostensibly a half-hour break, and when they got back, I was <strong>*still*</strong> waiting.
		And the wait continued quite a while.
		I didn&apos;t have a timekeeper on me though.
		If I weren&apos;t already planning to quit using this card, I&apos;d decide now to quit using it.
		I don&apos;t have time to deal with this every month!
	</p>
	<p>
		Anyway, it seems it&apos;ll take about three days for the bill credit to show up, so I have to wait until then to pay off the rest of the bill.
		That way, the tellers are able to pull up the actual balance so I can pay off what I really owe.

		My discussion posts for the day:

	<blockquote>
		<p>
			My main confusion seemed to come from not having been able to put it in practice yet.
			The very nature of these discussion assignments demands as early posting as possible, but the days off from work are typically on Tuesday and Wednesday.
			This week, I only had Wednesday (today) off.
			I didn&apos;t have time to complete the assignment for the week before posting my discussion assignment post.
		</p>
		<p>
			I finally got it as I was putting the finishing touches on my solution to problem 2.
			The inability of distance-vector routing to figure out ahead of time the path packets will likely travel results in endless loops like you described.
			It&apos;s a pretty poor system, and I&apos;m glad it&apos;s for the most part been replaced.
			There is no actual infinity as described by the book though; the book&apos;s description threw me <strong>*way*</strong> off course.
		</p>
	</blockquote>
	<blockquote>
		<p>
			That full view of the network is what prevents the looping problem.
			When a node notices a downed link, it reports it to all other nodes right away.
			Then, the other network nodes can check to see if an alternate path exists to that node.
			If not, they know it, and don&apos;t need to play hot potato with packets meant for the inaccessible node.

	<blockquote>
		<p>
			You make a good point that geothermal energy is available all the time, regardless of weather.
			Weather doesn&apos;t make it underground, so the high temperatures down there used for energy remain pretty consistent.
			Unfortunately, you&apos;re right, renewable energy has to compete with non-renewable energy in terms of monetary cost, and it doesn&apos;t always win.
			Even people that can afford the price difference often don&apos;t care enough to shell out the extra cash.
